TDS and Blackice why can't we get along

I am having problems with TDS. In the past It was working fine with blackice, now TDS will close by itself and when I run a full scan it will close. I am also using blackice PC protection. When I disable application protection in BI, TDS works fine. When I enable application protection in BI, TDS will load up but later on in the day it will abruptly close. So I think that BI is closing TDS and won't allow it to do a scan. I was wondering if anyone else has had this problem. I have checked my application settings in BI and they seem to be fine and no TDS dll is marked as block or terminate. Any help will be appreciated.
